FIRE-PROOF HANGING CEILING.

SPECIFICATION forming part of Letters Patent No. 303,438, dated August 12, 1884.

"Application filed April Q11, 1894. (No model.)

To all whom, it may concern.-

Be it known that l, LoUIs LAFOND, el' the city, county, and State of New York, have invented a neT and useful Improvement in Fire- Proof Hanging Ceilings, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying` drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of my improvement, illustrating its use. Fig. 2 is a sectional elevation of the saine, taken through the line a x, Fig. l. Fig. 3 is the same View as Fig. 2, but showing the improvement applied to perforated ceiling-tiles. Fig. 4 is a perspective View of a part oftheimprovement, the tiles being omitted.

The object of this invention is to obtain greater security in supporti ng ceiling-tiles.

The invention consists in a iire-proof hanging ceiling constructed with iron bars placed edgewise upon the flanges of the iron girders, and carrying the iron hangers that support the ceiling-tiles, whereby the said hangers and ceiling-tiles will be iirmly supported, as will be hereinaiterfully described.

' A represents the iron girders, the flanges of which support the arch I3, nia-de of tiles, concrete, or other suitable material.

C are iron bars placed edgewise, and thel ends of which rest upon the flanges of the girders A, and are built into the arch B. Upon the bars C are placed hangers D,'which are made of light iron bars or plates bent into U shape, and having the ends of their arms bent outward or from each other at right angles, as shown in Figs. 2 and 3, to support the ceilingtiles E. The ceiling-tiles E maybe madesolid, as shown in Figs. 1 and 2, in which case the said tiles rest upon the ilanges of the hangers D, or the ceiling-tiles E may be hollow or perforated, as shown in Fig. 3, in which'case the flanges of the hangers D are placed in the perforations of adjacent tiles E, so as to leave the lower surface of the said tiles smooth.

Having thus described niyinvention, I claim as new and desire to secure by Letters Patent- In a fire-proof hanging ceiling, the combination, with the iron girders A `and the iron hangers D, of the iron bars C, substantiallyT as herein shown and described, whereby the said hangers and the ceilingtiles are iirinly supported, as set forth.
